I've seen people in the Discord put out different ideas on what Chyos's intentions were, but I never asked him myself, so not sure. Honestly, never mattered to me because both routes make sense as canon, which is how it should be. I can't overstate how many devs fuck that up and make only one interpretation make sense; or even worse, make both not make much sense while trying to accommodate both.
If you want to treat the default relations as the real canon, go for it, as it doesn't matter much to me. Just don't expect a father (or any family, for that matter) to show up down the line.
